Des Weiteren enthält das Fahrzeug eine Steuerung, die zum Empfang von Eingangssignalen, die eine Fahrzeuggeschwindigkeit und einen Batterieladezustand (BSOC) anzeigen, und zur Deaktivierung des Antriebsmoments, wenn der BSOC unter einer Maximalentladungsgrenze liegt, konfiguriert ist. Des Weiteren ist die Steuerung zur Aktivierung von Nutzbremsung, wenn der BSOC unter der Maximalentladungsgrenze liegt und die Fahrzeuggeschwindigkeit über einer vorbestimmten Geschwindigkeit liegt, konfiguriert.A vehicle is provided with a motor configured to provide drive torque and enable regenerative braking. Further, the vehicle includes a controller configured to receive input signals indicative of a vehicle speed and a battery state of charge (BSOC) and to deactivate the drive torque when the BSOC is below a maximum discharge limit.

Description
Eine oder mehrere Ausführungsformen betreffen ein Fahrzeugsystem zum gesteuerten Abschalten eines Elektrofahrzeugs bei geringer Batterieleistung.One or more embodiments relate to a vehicle system for controlled shutdown of an electric vehicle at low battery power.
Der Begriff "Elektrofahrzeug", wie er hier verwendet wird, umfasst Fahrzeuge mit einem Elektromotor für den Fahrzeugantrieb, wie zum Beispiel batterie-elektrische Fahrzeuge (BEVs, BEV – battery electric vehicle), Hybridelektrofahrzeuge (HEVs, HEV – hybrid electric vehicle) und Plug-In-Hybridfahrzeuge (PHEVs, PHEV – plugin hybrid electric vehicle). Ein BEV enthält einen Elektromotor, wobei die Energiequelle für den Motor eine Batterie ist, die von einem externen Elektrizitätsnetz wiederaufgeladen werden kann. Bei einem BEV ist die Batterie die Energiequelle für den Fahrzeugantrieb. Ein HEV enthält einen Verbrennungsmotor und einen Elektromotor, wobei die Energiequelle für den Verbrennungsmotor Kraftstoff ist und die Energiequelle für den Elektromotor die Batterie ist. Bei einem HEV ist der Verbrennungsmotor die Hauptenergiequelle für den Fahrzeugantrieb, wobei die Batterie zusätzliche Energie für den Fahrzeugantrieb bereitstellt (die Batterie speichert Kraftstoffenergie und gewinnt kinematische Energie in elektrischer Form zurück). Ein PHEV ist wie ein HEV, aber das PHEV hat eine Batterie mit größerer Kapazität, die vom externen Elektrizitätsnetz wiederaufgeladen werden kann. Bei einem PHEV ist die Batterie die Hauptenergiequelle für den Fahrzeugantrieb, bis sich die Batterie auf eine niedrige Energiehöhe entleert, zu welchem Zeitpunkt dann das PHEV wie ein HEV für Fahrzeugantrieb wirkt.The term "electric vehicle" as used herein includes vehicles having an electric motor for vehicle propulsion, such as Battery Electric Vehicles (BEVs), Hybrid Electric Vehicles (HEVs), and Plug In-Hybrid Vehicles (PHEVs, PHEV - plugin hybrid electric vehicle). A BEV includes an electric motor, where the power source for the engine is a battery that can be recharged from an external electrical grid. In a BEV, the battery is the power source for vehicle propulsion. An HEV includes an internal combustion engine and an electric motor, wherein the power source for the engine is fuel and the power source for the electric motor is the battery. In an HEV, the internal combustion engine is the main source of energy for vehicle propulsion, with the battery providing additional energy for vehicle propulsion (the battery stores fuel energy and recovers kinematic energy in electrical form). A PHEV is like a HEV, but the PHEV has a larger capacity battery that can be recharged from the external electricity grid. In a PHEV, the battery is the main power source for vehicle propulsion until the battery deflates to a low energy level, at which point the PHEV then acts as a HEV for vehicle propulsion.
Das Elektrofahrzeug überwacht den Status der Batterie unter Verwendung mehrerer Messungen, einschließlich des Batterieladezustands (BSOC – battery state of charge). Der BSOC kann als ein Prozentanteil dargestellt werden, der die Energiemenge in der Batterie von 0% (leer) bis 100% (voll) darstellt. Batterien können beschädigt werden, wenn sie überladen oder zu stark entladen werden. The electric vehicle monitors the status of the battery using multiple measurements, including battery state of charge (BSOC). The BSOC can be represented as a percentage representing the amount of energy in the battery from 0% (empty) to 100% (full). Batteries can be damaged if overcharged or over-discharged.
Deshalb halten viele Elektrofahrzeuge nach dem Stand der Technik die Batterie innerhalb eines Betriebsbereichs zwischen einer Ladegrenze von ca. 80% BSOC und einer Entladungsgrenze von ca. 20% BSOC.Therefore, many state-of-the-art electric vehicles maintain the battery within an operating range between a charge limit of approximately 80% BSOC and a discharge limit of approximately 20% BSOC.
Bei einer Ausführungsform wird ein Fahrzeug mit einem Elektromotor versehen, der dazu konfiguriert ist Antriebsmoment bereitzustellen und Nutzbremsung zu ermöglichen. Des Weiteren enthält das Fahrzeug eine Steuerung, die zum Empfang von Eingangssignalen, die eine Fahrzeuggeschwindigkeit und einen Batterieladezustand (BSOC) anzeigen, und zur Deaktivierung des Antriebsmoments, wenn der BSOC unter einer Maximalentladungsgrenze liegt, konfiguriert ist. Des Weiteren ist die Steuerung zur Aktivierung von Nutzbremsung, wenn der BSOC unter der Maximalentladungsgrenze liegt und die Fahrzeuggeschwindigkeit über einer vorbestimmten Geschwindigkeit liegt, konfiguriert.In one embodiment, a vehicle is provided with an electric motor configured to provide drive torque and enable regenerative braking. Further, the vehicle includes a controller configured to receive input signals indicative of a vehicle speed and a battery state of charge (BSOC) and to deactivate the drive torque when the BSOC is below a maximum discharge limit. Furthermore, the control for activating regenerative braking when the BSOC is below the maximum discharge limit and the vehicle speed is above a predetermined speed is configured.
Bei einer anderen Ausführungsform ist ein Fahrzeugsystem mit einer Steuerung versehen, die zum Empfang von Eingangssignalen, die eine Fahrzeuggeschwindigkeit und einen Batterieladezustand (BSOC) anzeigen, und zur Deaktivierung von Antriebsmoment, wenn der BSOC unter einer Maximalentladungsgrenze liegt, konfiguriert ist. Des Weiteren ist die Steuerung zur Deaktivierung von elektrischer Bremskraftunterstützung und elektrischer Lenkunterstützung, wenn der BSOC unter der Maximalentladungsgrenze liegt und die Fahrzeuggeschwindigkeit unter einer vorbestimmten Geschwindigkeit liegt, konfiguriert.In another embodiment, a vehicle system is provided with a controller configured to receive input signals indicative of a vehicle speed and a battery state of charge (BSOC) and to deactivate drive torque when the BSOC is below a maximum discharge limit. Further, when the BSOC is below the maximum discharge limit and the vehicle speed is below a predetermined speed, the controller for deactivating electric brake assist and electric assist steering is configured.
Bei noch einer anderen Ausführungsform wird ein Verfahren zum gesteuerten Abschalten eines Elektrofahrzeugs bereitgestellt. Es werden Eingangssignale empfangen, die eine Fahrzeuggeschwindigkeit und einen Batterieladezustand (BSOC) anzeigen. Antriebsmoment wird deaktiviert, wenn der BSOC unter einer ersten Entladungsgrenze liegt. Nutzbremsung wird aktiviert, wenn der BSOC unter der ersten Entladungsgrenze liegt und die Fahrzeuggeschwindigkeit über der vorbestimmten Geschwindigkeit liegt.In yet another embodiment, a method for controlled shutdown of an electric vehicle is provided. Input signals indicating a vehicle speed and a battery state of charge (BSOC) are received. Drive torque is deactivated when the BSOC is below a first discharge limit. Regenerative braking is activated when the BSOC is below the first discharge limit and the vehicle speed is above the predetermined speed.
Das offenbarte Fahrzeugsystem bietet Vorteile, indem es einen Betrieb des Elektrofahrzeugs unter der Entladungsgrenze gestattet, wodurch die Batteriereichweite vergrößert wird. Das Fahrzeugsystem steuert das Abschalten des Elektrofahrzeugs, wenn der BSOC unter einer Maximalentladungsgrenze liegt, durch Deaktivierung von Fahrzeugantriebssystemen und Aktivierung von Nutzbremsung zur Bereitstellung von Energie für elektrische Bremskraftunterstützung und elektrische Lenkunterstützung.The disclosed vehicle system provides benefits by allowing the electric vehicle to operate below the discharge limit, thereby increasing the battery range. The vehicle system controls shutdown of the electric vehicle when the BSOC is below a maximum discharge limit by deactivating vehicle propulsion systems and activating regenerative braking to provide energy for electric brake assist and electric assist steering.
